Arp spoffing question

[Juan B <juanbabi () yahoo com>]

Hi,

I need to demonstrate Arp spoffing to my manager.
lets say that i have in the lab a pc names pc A a
Gateway and my pc-which is pc J.
I want that all the traffic from pc A and the Gateway
and vise versa will pass throw pc J. do I need to
connect PC J with two nic cards to the main switch or
with just one, as far as I understand I need to
connect it with 2 nics,am I wrong?

Thanks,

Juan
